Lisa Hatfield:

So regarding clinical trials right now, are there any clinical trials that you are conducting or that you’re particularly excited about for patients that they might want to ask their providers about?

Dr. Kami Maddocks:

Yes, so we’re also looking at opening a trial for frontline follicular lymphoma that looks at the use of bispecific antibodies. So I think that’s very exciting, because in general, it’s a well-tolerated therapy. And I think if it gives us a chance to produce very good outcomes, but without the toxicity of chemotherapy in the frontline setting, that to me is super exciting for patients.

We’re also looking at different bispecific antibodies. So they currently approved one target CD20. We have a CD19-targeted bispecific antibody that I also think is exciting to look at the potential for different targets because then once a patient has had one, you’re targeting something different, and the thought is that they might still be able to respond to a different one.

Lisa Hatfield:

Yeah. So with bispecifics then, is that continuous therapy, or is that limited duration therapy?

Dr. Kami Maddocks:

It actually depends on the bispecific. So in follicular right now, the one approved is for a limited duration. When you look at a few of the others that have been approved and other lymphomas that are being studied in follicular lymphoma, there’s a little bit of a variation between continued treatment and limited-duration therapy. I think what’s exciting about a lot of the combination studies is they are more looking at a defined period of time with the combinations.

Lisa Hatfield:

Which I’m sure a lot of patients love to hear that. Limited duration, there’s an end to this possibly, so yeah. 

Dr. Kami Maddocks:

Yeah. Nobody wants to be on treatment forever.

Lisa Hatfield:

Another patient is asking if you can speak to emerging treatment options for patients with relapsed/refractory follicular lymphoma?

Dr. Sameh Gaballa:

Yeah. So the field of follicular lymphoma is changing rapidly. I always tell patients that sometimes the best treatment is actually on a clinical trial because those are going to be the next generation of treatments that are going to get approved in the next few years. But right now we have the most effective therapy really is CAR T-cell therapy. CAR T-cell therapy by far is the most effective treatment we have at this time. It’s approved for patients who have had two or more lines of prior therapies. We also are investigating this. I actually have a trial here at Moffitt where we’re looking at CAR T-cell therapy as early as in the second line, in patients who have what we call the high-risk ones, the POD24. So a patient with POD24 follicular lymphoma relapsed in less than two years. We have a trial to investigate the role of CAR T-cell therapy in this setting. The other very promising group of treatments, again, is bispecific antibodies, again, currently approved in the third line, mosunetuzumab-axgb (Lunsumio).

But there are others coming up and have data on epcoritamab-bysp (Epkinly), as well as a lot of other bispecifics, as well as combinations. I mean, epcoritamab-bysp has also data presented with combination with lenalidomide. And right now, the follow-up duration is not very long, but so far, it looks extremely promising with very high response rates. So those also might be coming very soon. And, of course, once something works in the relapsed/refractory setting, we start looking at earlier lines of therapy. And actually, we’re now looking at trials in the first-line setting with some of these agents as well. Tazemetostat (Tazverik) is a pill. It’s also approved in the third-line setting, but we’re also investigating it. We have a trial here where we’re looking at combining it with standard rituximab (Rituxan), lenalidomide (Revlimid), so tazemetostat plus rituximab, lenalidomide as early as in the second line. So that also is interesting. And as I mentioned before, BTK inhibitors currently being looked at in trials might also have a role in follicular lymphoma very soon.

Lisa Hatfield:

And this patient is asking about the significance of bispecific antibody treatment. And you touched on that a little bit. It looks like she’s also asking if there are specific genetic or molecular markers that can predict a patient’s response. And if I try to translate that, maybe she might be asking about targeted therapy.

Dr. Sameh Gaballa:

Yeah, so bispecific antibodies and CAR T-cell therapy, they target something called CD, either CD19 or CD20, and that’s almost universally expressed on B cells. So most of your follicular lymphoma patients are going to be expressing CD19 or CD20. Tazemetostat is the pill that I talked about. It inhibits an enzyme called EZH2. Some patients have an EZH2 mutation where it seems to work very well. However, tazemetostat also works in patients who don’t have that mutation. So that’s why it’s not very important to check for the mutation.

It seems maybe it works better in patients who do have the mutation, but it does work as well in patients who do not have that mutation. So unlike other malignancies and other cancers, biomarkers are not yet driving a lot of our treatment decisions in follicular lymphoma as of right now.

Lisa Hatfield:

How exactly do bispecific antibodies engage the patient’s immune system to target and eliminate follicular lymphoma cells?

Dr. Sameh Gaballa:

So bispecific antibodies are a very interesting class of medicines. It’s an antibody that has two ends to it. So one end would target the patient’s own immune cells, meaning that they would attach the antibody to the patient’s own immune cell and then the other end of the antibody engages the cancer cell. So it’s basically hand-holding the patient’s own immune system to go and kill the cancer cell. And this is not just in lymphoma. It’s looked at in multiple myeloma as well, approved therapies there. And a lot of other cancers, we have bispecific antibodies being developed in clinical trials right now.

Katherine:                  

Well, Dr. Woyach, let’s start by understanding CLL. Would you briefly walk us through what CLL actually is?

Dr. Woyach:               

Sure. CLL is a cancer of the blood, the lymph nodes, and the bone marrow.

And it happens when a particular type of white blood cell called a B lymphocyte acquires genetic mutations and transforms into a cancer cell. And then, over time, those cancer cells continue to grow and divide. And they can cause symptoms such as enlarged lymph nodes if the cells get stuck in the lymph nodes and continue to grow there. It can cause a high white blood cell count, which usually doesn’t cause any symptoms but is one of the things that we see often in CLL. And then, it can also cause the bone marrow to not be able to produce normal cells because it can get so infiltrated or so full of CLL cells.

And this can cause things like anemia, which is lowering of the red blood cell count and thrombocytopenia, which is lowering of your platelet count.

Katherine:                  

What are the steps involved in reaching a diagnosis?

Dr. Woyach:               

CLL is an interesting disease because it’s one of the only cancers that does not require a biopsy of something for a diagnosis.

So, we can, actually, make the diagnosis of CLL based on the peripheral blood. So, just a blood draw in somebody’s doctor’s office. Usually, CLL is diagnosed in the asymptomatic stage. So, somebody goes to their primary care doctor, has blood drawn usually for another reason, and is found to have a high white blood cell count or sometimes even a fairly normal white blood cell count but a high percentage of lymphocytes. That certain type of cancerous white blood cell. So, the next step in the diagnosis then is something called peripheral blood flow cytometry, which is a specialized test where we look at the markers or antigens on the surface of white blood cells.

So, there is kind of a code of these markers on the surface of all of your blood cells that can tell what type of cells they are. So, for CLL in particular, we’ll see that the cells express some of the normal markers we would see on a normal B lymphocyte.

Things like CD19, CD20, CD23. But they also express a marker called CD5, which is found on normal T lymphocytes but shouldn’t be found on B lymphocytes.

And so, this collection of surface markers can make the diagnosis of CLL. Sometimes, we do need to do extra studies like a bone marrow biopsy or a lymph node biopsy. But often times, those are not necessary at the time of diagnosis.

Katherine:                  

When you meet with patients, Dr. Woyach, what are some common misconceptions that you hear about?

Dr. Woyach:               

I think the biggest thing that I hear, and granted I see a lot of patients after they’ve been diagnosed by someone, gone to see an oncologist and then, come to me after, but one of the common things that I hear is that somebody has told them along the way that they have the good type of cancer, which I think is not a very helpful thing to hear as a patient because, of course, no cancer is a good type of cancer.

I think it’s important to note that CLL is one that has a lot of treatment options and usually extended survival. But I think that’s one of the most common misconceptions that I hear.
